# Supervisor del ESCÁNER PIXEL V4 (:8773) — P0 (2026-08-06).
# Reemplaza el nohup suelto de run_pixel.sh, que NO revivía: un SIGSEGV de frida-core dejaba el escáner
# MUERTO hasta reinicio manual (horas de "bloqueo"). Aquí: prep de dispositivos UNA vez + backend con
# RESPAWN (throttle anti-flap) + log con ROTACIÓN (>> en vez de >; no se trunca en cada respawn -> forense).
# NO reinicia el juego si ya está vivo (respeta la sesión). Pensado para lanzarse desde launchd (boot) o a mano.
